CORE BENEFITS

Engineered for profile oxidation processes, this high-performance chiller adopts a full-liquid flooded screw compressor design to deliver precise temperature control and efficient heat exchange.

🌡️

Consistent Oxidation Quality

Maintains precise oxidation process temperature at 19.5°C inlet / 18°C outlet (±0.5°C precision), ensuring uniform coating thickness and significantly reducing reject rates.

⚡

High Energy Efficiency

Optimized screw compressor system and flooded evaporator design deliver maximum cooling output with high energy efficiency and superior heat transfer performance.

🛡️

Reliable in Harsh/Corrosive Environments

Engineered for continuous heavy-duty industrial use, providing stable thermal performance even under high load and demanding processing conditions.

🔧

Lower Maintenance Cost

Comprehensive protection logic and modular system design minimize unexpected shutdowns and simplify routine maintenance procedures.

TECHNICAL FEATURES

Semi-Hermetic Screw Compressor System

Equipped with 1-2 high-efficiency screw compressors, supporting 10%–100% stepless capacity control to precisely match dynamic process loads.

Flooded Evaporator Design

Maximizes heat exchange efficiency and ensures highly stable outlet temperature for oxidation tanks (19.5°C inlet / 18°C outlet.Features a specialized anti-corrosion design for long-term durability in chemical environments.).

Industrial-Grade Heat Exchangers

Robust shell-and-tube condenser with optimized water flow patterns, specifically engineered for continuous operation.

Comprehensive Safety System

Integrated safeguards including PLC-based smart control, acid pump interlock, phase loss/reverse protection, over-voltage monitoring, and automatic emergency shutdown.

IDEAL APPLICATIONS

✓ Aluminum & Section Bar Oxidation Lines
✓ Metal Surface Treatment Industries
✓ Industrial Anodizing Plants
✓ Processes Requiring Strict Thermal Control

Technical Notes:

  • Standard Condition: Cooling capacity is based on chilled water outlet temperature of 7°C and inlet temperature of 12°C.
  • Oxidation Process Condition: Based on tank liquid inlet temperature of 19.5°C and outlet temperature of 18°C.
  • Performance Note: If the actual operating temperature is above 15°C, the cooling capacity will increase by more than 30%.
  • Noise Test: Noise is measured 1 meter in front of the main unit at a height of 1.5 meters, with average four-point values (ambient noise below 30dB).
